Why is Anti-Static Foam Pink?

Anti-static foam is pink because of a pink additive that is introduced during the manufacturing process of the foam. The color pink is used because it is an industry standard and most other common foam applications don’t use pink. Therefore by using the color pink the foam is easily identified and not easily mixed with non-anti-static foam. When considering the importance of using anti-static foam in static sensitive applications, it is generally accepted the bright color of the foam can be overlooked because the trade off of having identifiable anti-static material far outweighs the awkward color of the material.

Using the color pink however is not a requirement or law, but rather a choice made by foam manufacturers. Although it may be difficult to find anti-static foam in a different color it doesn’t mean a different color such as black is not available. If you are working on a project that requires a decent amount of material in which you can meet minimum order requirements, you can purchase anti-static material made in any other color. Be warned however it is impossible to tell the difference between black anti-static foam and standard foam.

What is Anti-Static Foam?

Anti-Static foam (also known as anti-stat foam) is a form of foam which has a chemical agent that will not create a static charge when rubbed against itself. The foam will allow static charges to pass through it in essence protecting your sensitive equipment & not passing the charge into your items. Anti-stat foam is dyed pink for visual identification & generally cannot be bought in other colors without a minimum volume order. Why pink? It has been like that since the beginning of time & no one really knows.

Remember this: when creating an anti-stat insert which will fit inside of a case to use anti-stat foam in the lid as well. People often forget this and will use regular convoluted foam in the lid rather than anti-static foam. This will defeat the purpose altogether of using anti-static foam in the base.

Now for the big question… Should you buy your foam insert with anti-static foam or not? Generally speaking if you are not sure then the answer is usually no. With that being said if you are not sure, but the foam is within your budget & you are putting sensitive electronic equipment in the case then go for it as it can’t hurt.
